BERT E. HILL, or PITTsBUne, KANSAS.

COMPRESSOR.

Y Be it known that I, BERTE. HILL, a citizen ofthe United States, residing at Pittsburg, in the county of Crawford and State of Kansas, have invented certain new and useful Improvements in Compressors, of which the following is a specification.

My invention relates to air, ammonia *or other compressors, and particularly contem .to indicate like parts in each embodiment of my invention, and in which,

Figure 1 is avertieal sectional view through my lmpro'ved compressor showing certain' parts in side elevatlon, Fig. 2 is a cross section therethrough taken on the line 2-2 of Fig. 1, Fig. 3 is a similar view to Fig'. 1 showlng anl arrangement of parts constituting a' modified form of my invention,-and Fig. 4 is a crosssection therethrough on the line 4 4 Y of Fig. 8.

In the practical embodiment of my invention, and with particular reference j to the' form thereof illustrated in Figs.,1 and y2, l

.provide a structure `comprising a substantially circular cylinder 1 mounted onthe base 2, and having a portion 3 therofextending vertically therethrough, and provided with anl elongated slot 4, in which a sliding gate 5 is adapted to operate. The casing 1 is pro-` vided .with the cylinder heads 6 and 7- bolted thereto, the c linder head 6 providing an end bearing 8 or the driven shaft Qcarrying the cam rotor 10, keyed thereto within the circular cylinder 1. The cylinder 1 is pro- Yvidedl with an inlet aperture ornozzle 11y within which is threadedly engaged an'inlet pipe 12, The sliding gage 5 is provided With an extended piece 13 at the lower' end thereof, which, in conjunction with said gate is adapted to close the inlet nozzle 1 1 when said gate is' forced upward within the slot 4 against the tension of a spring 14therein until the lextension .13 engages with the edge of the cylinder 1. The cam rotor 10 is provided With a movable section 15, spring pressedk into slidingv engagement with the specificati@ of Leiters Patent'. Appiimiqn filed June 12, 1907. seriai'uo. 378,615.

maniac-Apes a laca inner circumference. of the cylinder `1 means of coil springs 16. Thus it v seenv that as the rotor 16=fis moved lin the direction of the ari-'ow shown in Fig, 1, thev air, gas, or the like, will be compressed With in the cylinder 1 between the cam portieri of said rotor and the sliding gate 5, a new char e being received through the inlet nozzle f -1 behind said cam portion as said rotor moves,

andas the gate'5 slides downwardiy' agafgnst the periphery of said rotor 10.

` rI he outlet for the compressed charge is arranged upon the opposite side ,of the gate 5 from the inlet 11, and comprises a bu 17 screwed within the cylinder 1, and ro vided Ywith openings 18 lying .within anI annular recess 19 within said cylinder wall v Which has connected with and arranged therein the outlet pipe 20. Thebushing 17 is provided with 'a cap 21, and has formed with its inner circumference a valve seat for the rece tion of a valve '22, having its stem arrange within a guiding socket 23 in the cap 21, a strong coil spring 24 beingarranged between said valve and said soc et 23 to hold said valve tightly upon its seat until the pressure of the charge Within the cylinder 1,

ycaused by the movement ofy therotor 10,

reaches a 'predetermined de ee,-at which time said valve will be move away from-its seat to lallow the, charge to pass from the cylinder 1 through the outlety pipe 21. The

4cylinder head.7 is` provided with packing a recess,v u onthe inner face of said cylinder head and a justably .pressed against the preripheral'l 'edge ofthe rotor 10 by means of t r1ngs25 seated in a circumferenti e adjust` ing'screws 26.

nthe modiiiedform of my invention, asl .shown inFigs. 3 and 4, it will be seen by reference thereto, that the same consists sim-l ply in. reversing the elements contained in lgs. 1 and 2, in other Words,- in turning.

Figs. land 2 upside down.A This form includes all ofthe elements shown in Figs. 1 and 2, and of exactly the same constructlon,

the inlet and outlet pipes 12 and 2O being l arranged atthe bottom of the cylinder-1 to substantiall ression o ammonia, inasmuch as' any iquid which'mayl have gotten into the cylinder 1 will at once settle in the base thereof,

adapt the same for the comand will be readily forced through the outlet1 valve,`settling then Within theannular recess 19.

Having thus fully described my invention I claim:

1. In a` compressor of the character described, the combination of a casing hav` ing a slotted extension and a recess there on adjacent said extension, a driven shaft mounted centrally through said casing and provided*r with a 'cam rotor mounted thereon Within said casin a iuid inlet for said casing opening' throng said recess, a sliding gate arranged within said slotted extension of-said casing and rovided with a shoulder extending there om and fitting within said recess, said gate-being spring pressed into enga ement with the periphery of said rotor an being adapted with its shoulder to close said inlet 'when forced outwardly by the cam, 'and a pressure regulated outlet arranged through said casing adapted to receive the compressed charge, substantially as described.

, 2. n a ,compressor of the character described, the combination of a casing having a slotted extension and a recess ad] acent said extension, a driven shaft mounted centrally through said casin and provided with a c am rotor-mounted t ereon Within said f and casing, a fluid inlet for said casing openn through said recess, a sliding gate arrange within said slotted extension of said casing rovide'd With a shoulder extendin there om and fitting Within said recess, sai gate being spring pressed into enga ement with the periphery of said rotor an being adapted With its aforementioned shoulder to cl'ose said inlet when forced downwardly by said cam, an outlet for said'easingiorming a valve seat, a valve seated upon said 'seat with its cam projecting outwardly from said: casing, a cap' t eadedly engaging Within thewalls 'of said casing vand having a central socket portion iog a guide for said valve stem, andl a s ring interposed between said valve and sai socket portion to allow said valve to 'o en When upon a desired pressure, substantie y as described.

In testimony whereof I aiix my signature
